Thanks for posting this info. It would be nice if Altera published the op-codes issued during Active Serial mode configuration.

The EPCS devices I have looked at have ID codes that match Numonyx parts (which Micron supplies).

The M25P are the EPCS parts, the N25Q are most likely the EPCQ parts.

Since these parts are footprint compatible with the Spansion parts, you should be able to confirm that these parts support the opcodes mentioned by Altera, and then use them on your board.

Cheers,

Dave
